Gas Analyzers

Overview

The CALOMAT 6 gas analyzer is primarily used for quantitative determination of H2 or He in binary or quasi-binary gas mixtures.

Concentrations of other gases can also be measured if their thermal conductivities differ significantly from the residual gases like Ar, CO2, CH4, NH3.

Function

Mode of operation

The measuring principle is based on the different thermal con-ductivity of gases.

The CALOMAT 6 sensor is a micromechanical-made Si chip with a measuring membrane and thin-film resistors.

The resistors are adjusted on a constant temperature. This re-quires an current intensity depending on the sample gas thermal conductivity. Further this „coarse value“ is electronically pro-cessed and used to calculate the gas concentration.

The sensor is located in a thermostatically-controlled stainless steel enclosure in order to prevent influences of ambient temper-ature changes.

To prevent the influences by the sample gas flow changes, the sensor is not placed in the main flow.

Note

The sample gas needs to be free of dust. Condensate in the cells must be avoided. That is why the most measuring tasks require an appropriate gas preparation.

CALOMAT 6, mode of operation

Special characteristics• Four freely-progammable measuring ranges, also with zero

offset, all measuring ranges linear• Smallest spans up to 1% H2

(with suppressed zero: 95 to 100% H2) possible• Electrically isolated analog output 0/2/4 to 20 mA

(also inverted)• Autoranging or manual range switching possible; remote

switching is also possible• Storage of measured values possible during calibration• Time constants selectable within wide limits (static/dynamic

noise suppression); i.e. the response time of the analyzer can be matched to the respective application

• Short response time• Low long-term drift• Measuring point selection for up to 6 measuring points

(can be parameterized)• Measuring range identification• Measuring point identification• External pressure sensor for correction of pressure variations

in sample gas• Automatic range calibration can be parameterized• Operation based on NAMUR Recommendation• Two operation levels with separate access code to prevent

unintentional and unauthorized inputs• Simple handling using a numerical membrane keypad includ-

ing operator prompting

• Customer-specific analyzer options such as e.g.: - Customer acceptance- Tag labels- Drift recording- Clean for O2-Service.

Spans

The smallest and largest spans which are possible depend on the measured component (type of gas) as well as the respective application.

The smallest possible spans listed below refer to N2 as the resid-ual gas. With other gases which have a larger/smaller thermal conductivity than N2, the smallest possible span is also larger/smaller.

Influence of interfering gases

Knowledge of the sample gas composition is necessary to determine the influence of residual gases with several interfering components.

The following table lists the zero offsets expressed in % H2 re-sulting from 10% residual gas (interfering gas) in each case.

For residual gas concentrations differing from 10%, the corre-spondant multiple of the table value gives an acceptable ap-proximation. This is valid for for residual gas concentrations up to 25% (dependent on gas type).

The thermal conductivity of most gas mixtures has a non-linear response. Even ambiguous results, such as e.g. with NH3/N2 mixtures, can occur within a specific concentration range.

In addition to a zero offset, it should also be noted that the gra-dient of the characteristic is influenced by the residual gas. How-ever, this effect is negligible for most gases.

In case of correction of the influence of interfering gases with additional analyzers (ULTRAMAT 6/ULTRAMAT 23), the resulting measuring error can – depending on the application – amount up to 5% of the smallest measuring range of the application.

PROFIBUS DP/PA

PROFIBUS DP/PA is the leading field bus on the market. All Siemens gas analyzers are suitable for PROFIBUS when equipped with an optional plug-in card (retrofitting also possible) and satisfy the binding "Device profile for analyzers" defined by the PNO (PROFIBUS user organization). Central access to the analyzers in the system is possible using the SIMATIC PDM operator input software.

The term field bus describes a digital communications system with which distributed field devices in a plant are networked to-gether via one single cable, and connected at the same time to programmable controllers or to a process control system. PROFIBUS is the leading field bus on the market. The PROFIBUS DP version is widely used for production automation because of its high transmission rate for relatively small data quantities per device, whereas PROFIBUS PA particularly takes into account the features required for process engineering, e.g. large data quantities and application in potentially explosive at-mospheres.

User benefits can be found in the extremely high potentials for cost savings in all areas of the plant, covering configuring and commissioning, operation and maintenance, and up to later plant extensions.

Operation of the gas analyzers from a control system or separate PC is possible using the SIMATIC PDM (Process Device Man-ager) operator input tool which is software executing under Win-dows and which can also be incorporated into the SIMATIC PCS 7 process control system. This permits clear dis-play of both the incorporation of devices into the system and the complex parameter structure of the analyzers, permitting opera-tion to be carried out simply by clicking.

The PROFIBUS user organization (PNO) is an independent inter-national institution, and represents the interests of many vendors and users. In addition to services such as consultation, training and device certification, its prime task is the further develop-ment, standardization and promotion of the PROFIBUS technol-ogy. The definition of a binding functionality for a device class in a profile is a prerequisite for the uniform response of devices from different vendors, the so-called interoperability.The profile for analyzers was defined as binding at the end of 1999, thus guaranteeing the interaction of all PROFIBUS-based devices in a plant.

This profile defines the functionality of the analyzers in a block model: e.g. the physical block describes the measuring proce-dure, analyzer and vendor names, serial number and operating state (operation, maintenance). Various functional blocks con-tain the execution of specific functions such as the processing of measured values or alarms. The transducer blocks describe the functionality of the actual measuring procedure and its con-trol, e.g. preprocessing of a measured value, correction of cross-interferences, characteristics, measuring ranges as well as switching and control procedures. Protocols define the data transmission between the stations on the bus.

A differentiation is made between cyclic and acyclic services. Cyclic services are used to transmit time-critical data such as measured values and statuses. The acyclic services permit the scanning or modification of device parameters during operation.

All gas analyzers of Series 6, (ULTRAMAT 6, OXYMAT 6/61, CALOMAT 6, FIDAMAT 6) as well as the ULTRAMAT 23 are suit-able for PROFIBUS when fitted with the optional plug-in card.

Explosion-proof design


Application

Use of the CALOMAT 6 in hazardous areas

Suitability-tested field analyzers of series 6 must be used to measure gases in hazardous areas. The preferred explosion protection for these analyzers is the pressurized enclosure EEx p for zone 1 or the simplified pressurized enclosure EEx n P for zone 2. In addition, these analyzers must be connected to monitoring equipment which must also be suitability.

Exception: a pressurized enclosure is not required in zone 2 for the measurement of gases whose composition always remains below the lower explosion limit (LEL); in this case, it is sufficient for the field housing to be gas damp-proof (type of protection EEx n R).

Following pre-purging of 5 minutes, the monitoring equipment ensures that no gas damp can enter the housing, and accumu-lation of the samples gas in the housing is prevented. The vol-ume flow during the pre-purging phase is > 50 l/min. The protec-tive gas is usually fed into the analyzer housing from a supply network via the monitoring equipment.

Category ATEX II 2G (Ex zone 1)

Two versions of pressurized enclosure EEx p complying with the directive 94/9/EC are available for use in zone 1:• Pressurized enclosure with compensation of losses resulting

from leaks Only that volume of protective gas required to hold an over-pressure of at least 50 Pa compared to the sample gas pres-sure and atmospheric pressure is fed into the housing. The maximum purging gas pressure is 165 hPa; this causes a max. permissible sample gas pressure of 160 hPa.Test certificate: PTB 00 ATEX 2022 XAnalyzer identification: II 2 G EEx p [ia] ia IIC T4

• Pressurized enclosure with continuous purging Protective gas continuously flows through the housing with a volume flow of at least 1 l/min; furthermore, the flow results in an overpressure in the housing of at least 50 Pa compared to atmospheric pressure.The max. permissible purging gas pressure is 25 hPa. The max. permissible sample gas pressure is equivalent to the permissible analyzer sample gas pressure. Test certificate: TÜV 01 ATEX 1708 XAnalyzer identification: II 2 G EEx p [ia] ia IIC T4.

The fundamental safety requirements are satisfied by compli-ance with the European standards EN 50014:1997, EN 50016:1995, EN 50020:1994 and EN 954:1996.

The EEx p monitoring equipment is a stand-alone unit which is connected electrically and pneumatically to the analyzer. Ex pro-tection is only provided when these two units are connected to-gether.

Category ATEX II 3G (Ex zone 2)

Two versions complying with directive 94/9/EC are available for use in zone 2: • Ex protection resulting from gas damp-proof housing

The housing is sealed sufficiently such that gas damp cannot penetrate. With this type of protection, only sample gases may be connected which are below the LEL.Test certificate: TÜV 01 ATEX 1686 XAnalyzer identification: II 3 G EEx n R II T6

• Simplified pressurized enclosure with continuous purging This type of protection must always be selected if flammable gases are to be connected. Protective gas continuously flows through the housing with a volume flow of at least 1 l/min; furthermore, the flow results in an overpressure in the housing of at least 50 Pa compared to atmospheric pressure. Manually controlled pre-purging with the analyzer power supply switched off is sufficient for the sim-plified pressurized enclosure. It is not necessary for the ana-lyzer to be switched off automatically should the protective gas fail.Test certificate: TÜV 01 ATEX 1697 XAnalyzer identification: II 2/3 G EEx n P II T4.

The fundamental safety requirements are satisfied by compli-ance with the European standards EN 50021:1999, EN 60079:1997, Sec. 13 and ZH 1/10, Sec. 1.

The EEx nP monitoring equipment is a stand-alone unit which is connected electrically and pneumatically to the analyzer. Ex pro-tection is only provided when these two units are connected to-gether.

Category ATEX II 3D (Ex zone 22)

Ex zone 22 concerns the so-called dust protection. This is the European successor to the previous German zone 11. Zone 22 concerns the area "in which during normal operation it is not ex-pected that potentially explosive atmospheres occur in the form of a cloud of flammable dust in the air. Should such a cloud oc-cur, however, then only briefly.

Considering the tightened conditions for zone assignment, for which now 13 possible ignition sources have to be taken into consideration, it can be expected that there will be increased demands for dust-protected analyzers.

The field versions of CALOMAT 6, OXYMAT 6 and ULTRAMAT 6 can be used in this zone according to the conformity statement TÜV 03 ATEX 2278 X.

They are assigned the Ex identification II 3 D IP65 T60 °C or T65 °C or T85 °C or T135 °C.

However, this only concerns the so-called external Ex protection. With respect to the measurement of flammable gases, the addi-tional measures applicable to gas explosion protection apply in addition, such as flame inhibitors. These separate certificates apply here.

FM Class I Div. 2

The same applies here as to the simplified pressurized enclo-sure with continuous purging; the required Ex protection is only provided when appropriate equipment is connected.

Type of protection and flame arrester

It generally applies that selection of the protective gas and use of flame arresters depend on the type of sample gas:• Connection of combustible gases above the LEL always re-

quire an inert gas (e.g. N2) as the protective gas. Furthermore, the process must be protected by flame arresters if it cannot be excluded that explosive gas mixtures could occasionally be present in the sample gas path.

• Gas mixtures which could be frequently or permanently explo-sive must not be connected!

• With gases below the LEL, air can also be used as the protec-tive gas, and flame arresters can be omitted.

Overview

BARTEC EEx p control unit „Leakage compensation“

The APEX 2003.SI/A2 control unit controls and monitors the prepurging phase and the operating phase of gas analyzers with „Containment Systems“ in Ex zone 1.

The control unit redundantly monitors the set overpressure of the purging gas. When the overpressure decreases, it is corrected to the adjustable setpoint (max. purging gas pressure 165 hPa).

Additional function

Due to the connection of additional pressure sensors, the inter-nal pressure of the enclosure is maintained at a pressure higher than the sample gas with a proportional valve. During the prepurging phase the purging gas flow is max. 4100 Nl/h with an internal enclosure pressure of 50 hPa.

4 programmable relay inputs (8 relay contacts) are available to separate the data lines.

Overview

BARTEC EEx p control unit „ Continuous purging “

The APEX 2003.SI/A4 control unit controls and monitors the prepurging phase and the operating phase of gas analyzers with „Containment Systems“ in Ex zone 1.

The control unit redundantly monitors a continuous current of protection gas through the connected analyzer and thereby di-lutes the eventually appearing sample gas below the lower ex-plosive limit (max. purging gas pressure 25 hPa).

4 programmable relay outputs (8 relay contacts) are available to interrupt the data lines.

Ex version: additional units Class I Div. 2Ex purging unit MiniPurge FM


Application

The Ex purging unit MiniPurge FM is used to monitor the pres-sure during continuous purging of an analyzer with purging gas or inert gas. If the pressure falls below the set value, an optical display is triggered and the relay is activated. This monitoring unit is driven by the purging gas pressure and therefore does not require an additional power supply.
